    ipq806x: 5.15: drop arm override compile patch
    
    Drop arm override compile patch. The use is dubious and at times (2016)
    it was never explained why this was required.
    Krait CPU and Cortex-a15 may be similar but they have some intrinsic
    difference. While very similar they differ a lot in additional feature
    and also cache configuration.
    
    Also these conflict with raid6 libraty compilation that use specific
    workaround not compatible with cortex-a15 and produce compilation
    warning.
    Fix compilation warning:
    cc1: error: switch '-mcpu=cortex-a15' conflicts with switch '-march=armv7-a+simd' [-Werror]
    cc1: all warnings being treated as errors
